To all wiwm t may concern."

Be it known thatl, ROBERT A. Evans, a citizen of the United States, residing at Mogollon, in the county of Socorro and State of New Mexico, have invented certain new. and useful Improvements in Gil-Burners, of which the following is a specification.

rlhis invention relates toan improved oil burner and the principal object of the invention is to provide an oil burner so constructed that the air and the oils may be kept in the same tank, the air serving as means for feeding the oil to the mixing chamber in which it is mixed with the air and the mixed air and oil then passing to the combustion chamber.

Another object of the invention is to provide an improved type of mixing chamber wherein the air and oil will be mixed thus producing a combustible mixture passing through an outlet nozzle and into a combustion chamber positioned within the stove.

This invention is-illustrated in the accom- 'panying drawings, wherein igure 1 is a view showing the structure in elevation, the combustion chamber being omitted and the tion, p o

Fig. 2 is an enlarged view showing the mixing chamber and combustion chamber in longitudinal section, the pipe leading from the mixing chamber and nozzle communieating withv the combustion chamber being own in elevation,

' The receptacle or tank 10 is provided with an inlet pipe 11 through which oil may be poured into the tank, the inlet pipe being provided with a control valve 12 and a unnel 13, the funnel permitting the oil to be An oil outlet pipe 14 leads from the bottom of the tank and is provided with a control valve 15 and communicates with the head 16 of the mixing chamber 17, a control valve '18 being 0- sitioned between the valve 15 and the head 16 so that the valve 18 may be opened the proper amount and left at this point, the valve 15 being opened and closed when operating the burner system.

A plump 19 is mounted upon a bracket 20 carried by the receptacle 10 and is provided with an inlet pipe 2l and an outlet pipe 22, these pipes being provided with check valves 23 and the pipe 22 communicating with the upper portion of 'the tank 10. An outlet pipe 24 leads from the top of the tank or receptacle 10 and communicates with the head 16 ofthe mixingnhamber, the pipe being provided with the .valves 25 and 2o which are similar to the valves 15 and 18, the valve 26 being open a certain that the proportion of air and oil will be in the proper relation and the valve 25 being amount so y.

opened and closed according to whether the device 1s in use or not. It will thus be seen that certain of these valves will at all times be left at a set position whereas the two remaining valves will be open or closed according to whether the machine is in operation. A gage 27 is provided so that the pressure of the air in the tank can be easily ascertained. In order to actuate the pump there is provided a pitman 28 leading Jfrom the head 29 sliding in the pump cylinder l and connected with the crank shaft 30 upon which there is mounted the disk 31. This disk 31 may be turnedby the handle 32 or may be rotatediby means of a belt leading fromaJ suitable source of power such for instance as an engine.

The mixing chamber 17 is provided with the inlet head 16 and outlet head 33, these heads being connected with the body and the inlet head being provided with the air and oil inlets 34 an 35 communicating with the annular groove 36. A cylinder 37 is mounted inthe body of this mixing chamber and held in place by the set lscrew 38 and is 'provided with grooves 39 which cross as shown in Fig. 2 and communicate at one end with the groove 36 and at the opposite end with the pockety 40 formed in the head 33. As-the oil and air pass around this cylinder 37 through the cross grooves 39, the streams of oil will be broken up by the air and the mixed air and oil will pass into the chamber 40 and through the pipe 41 leading therefrom into thevnozzle 42. This pipe 41 is provided with a control valve 43 so that the passage of the mixed air and oil The outlet nozzle 42 is provided with a tapered end 44 which fits into the nipple 45 leading from the head 46 of the combustion chamber 47 and is provided with a reduced outlet 'opening 48 through which the mixed airand oil will pass into the .nipple 45 and through this nipple into the Vcombustionchamber where it willbe ignited and the flames pass out through the openings 49. It should be noted that these openings 49 are formed in the upper and side portions of the combustion chamber and that therefore the Hames will be well distributed thus permitting it to very easily and quickly heat the stove.

When in use, the combustion vchamber is placed in the fire box of the stove and the nozzle 42 is passed through the door of the stove and inserted in the nipple 45. The oil is poured into the tankthrough the pipe 11 and the valve 12 is then closed. Valves 15 and 25Will also be closed and thepump then operated thus placing the air inthe upper portion of the. tank under the requlred amount of pressure. The valves 15 and 25can now be opened and the oil and air will pass through the pipes 14 and 24 into the annular groove 36 from which they been obtained, the valves will be left at the will pass through the grooves 39 into the chamber 40. As previously explained, the

currents of air and oil will be-broken durset position and the valves 15 and 25 opened I and closed when it is desired to use the device or stop the operation thereof.

What is claimed is 1. In an oil burner, a tank provided with an oil inlet, an oil outlet pipe leading from the lower portion of the tank, means for 'providing compressed air in the upper portion of said tank, an air outlet pipe leading from the upper portion of the tank, a mixing chamber having in one end inlets for the air and oil pipes communicating with an annular groove forming a-pocket, a cylinder in the chamber provided with grooves leading from the pocket to a second pocket in the opposite end portion of the mixing chamber and intercrossing, at points intermediate the length of the cylinder, and an outlet pipe for the mixed air and oil leading from the second pocket.

2. In an oil burner, a source of air and oil supply, pipes leading therefrom, a mixing chamber having a hollow body, heads at the ends of the body, the head at one end being provided with a pocket communicating with the inlets for the air and oil pipes, and the head at the opposite end of the body being provided with a pocket communicating with an utlet, and means to break the air and oil into streams and lead to the pocket of the second head with the streams of air and oil intersecting.

3. In an oil burner an air and oil supply tank having oil in the lower portion thereof and compressed air in the upper portion thereof, an oil outlet pipe leading from the tank, an air outlet pipe leading from the tank, a mixing chamber having a hollow body, heads at the ends of the body, the head 'at one end being provided with lan annular groove in its inner face communicating with inlets for the air and oil pipe and the head at the opposite end of the body being provided with a pocket communicating with an outlet, and means to break the air and oil into streams and lead the same to the pocket of the second head with the streams of air and oil intersecting.

4. In an oil burner, a supply tank having oil in the lower portion thereof yand compressed air in the upper portion thereof, an oil outlet pipe leading from the tank, an air outlet pipe leading from the tank, a mixing chamber having a housing provided at one end with air and oil inlets communicating with a pocket, a cylinder within the housing provided with longitudinally extending grooves leading from the pocket and interfs'e'cting and communicating with the pocket in the opposite end of the mixing chamber, and an outlet pipe. leading from the second pocket of the housing.

5. An oil burner including a source of air and oi1 supply, pipes leading therefrom, and a mlxing chamber having a body, a cylinder in the body provided with mixing grooves extending longitudinally thereof in intersecting relation, a head for said body provided with air and oilfinletscommunicating with a pocket having communication with the grooves of said cylinder, and a head for the opposite end of the body provided with a pocket to receive the mixed air and oils, the pocket of the second head communicating with an outlet.

In testimony whereof I ailix my signature in presence of two witnesses.
